Parts not stamped IHC should have letter codes. Here is a all correct IHC rifle of mine that you can compare parts to https://www.gunandgame.com/threads/latest-acquisition-ihc-garand.162069/ Is the stock IHC? Is there numbers stamped in the barrel channel? DOD stamp on the side? Post a pic of what is stamped on the side of the barrel. You cannot go by CMP prices as they did not sell correct IHC rifles. If your rifle is all correct IHC,I would say you are in the $2500 range. Best bet is to take very detailed pics and put it on Gunbroker.
